Title: Yarn winding control - for regulating the length of yarn wound on the bobbins of a spinning machine
IPC: D01H13/32
Filed: 1974-10-07
Abstract: Regulation of the length of yarn accumulated as a bobbin on spinning frames, partic. open end spinning frames, having a series of spinning stations, employs a signal representing the length of yarn collected on a yarn transporting shaft common to all the spinning stations and in addn., signals for starting and stopping counting derived from a stop motion in each spinning station or from an analogue signal generator.
